IMPROVEMENT IN COMBINATION PADLOCKS.

Specification forming part of LottersPatent No. 135,992, dated February18, 1873.

To all whom it may concern:

Be it known that I, JOSEPH KITTLE, of East Bend, in the county of Yadkinand State of North Carolina, have invented a new and useful Improvementin Combination Padlock, of which the following is a specification:

Figure 1 is a plan-view of my improved padlock, the upper part of thebody or case being removed. Fig. 2 is a longitudinal section of the sametaken through the line :20 w, Fig.1. Fig. 3 is a cross-section of thesame taken through the line y 9 Fig. 1.

Similar letters of reference indicate correspondin g parts.

My invention has for its object to furnish an improved combinationpadlock, simple in construction, convenient and reliable in use,inexpensive in manufacture, and almost impossible to be unlocked withoutknowing the The invention consists in the mode of combining, with theindexrods that receive the staple of a padlock in their grooves, a rodplaced transversely thereto, and work ing in grooves thereof,ashereinafter fully de scribed.

A B are the two parts of the body or case of the lock whicharedesigned'to be riveted or otherwise securely attached to each other. Cis the staple, one arm of which is made long and the other short forconvenience in passing it through the hasp, staple, or other object tobe locked. The arms of the staple 0 enter and fit into holes in the bodyor case A B, which holes may be formed partly in each part of the saidbody or caseA B. Upon the inner end of the longer arm 'of the staple Ois formed, or to it is attached, a toe or stop, D, which works in arecess in the body orcaseAB to prevent the staple from being drawn outany further than enough to allowthe short arm of said staple to bepassed through the thing to be locked. E are rods or shafts, which areinserted in transverse holes in the opposite shafts E when said staple Gis pushed in, are

formed semicircular notches, as shown in Figs. 2and 3, and in one sideof each of the shafts E, at the point where the long arm .of the stapleG crosses them, is formed a semieircir lar notch, as shown in Figs. 2and 3.

By this construction, when all the rods or shafts E are turned so thattheir notches are toward the long arm of the staple O, the staple isunlocked, and may be drawn out as far as the stop 1) will allow. This itwill be almost impossible to do without knowing upon what side of eachof the shafts E the notch is formed, as, if even one of said shafts isonly partially turned, the staple G will be held securely.

Upon the outer end of each ofv the shafts E is formed, or to it isattached, a disk, wheel, or knob, G, upon the edges of which are formedletters, figures, or other marks, one of which is directly opposite thenotch in said shaft, so that, by knowing this particular mark of eachshaft, the said shafts may be readily turned into the desired position.

Having thus described my invention, 1 claim as new and desire to secureby Letters Pat ent The combination, with rod F and notched staple O, ofthe index-rods E .G, annularly grooved to receive the former, andtransversely notched to allow the latter to operate therewith, asdescribed, and for the purpose set forth.

JOSEPH KITTLE.
